Explanation:

• Setting the wash time on a washing machine's digital control panel involves interacting with a computer - based interface (the control panel) without consciously thinking of it as using a computer.
• Activating a robot to vacuum an apartment: Robots are programmed (using computer logic) and when activated (e.g., via a smart - home system which is computer - controlled), one may not realize the computer aspect.
• Driving to the store in a car: Modern cars have computer systems (e.g., engine control units, navigation systems which may be integrated or used via a connected device like a smartphone in a non - obvious computer - usage way).
